CVE-2023-32191

Estado: AplazadaCrítica (9.9)—

When RKE provisions a cluster, it stores the cluster state in a configmap called `full-cluster-state` inside the `kube-system` namespace of the cluster itself. The information available in there allows non-admin users to escalate to admin.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Acceso de red con privilegios (PR:L) a servicio Kubernetes remoto permite leer configmap sensible y escalar a admin; CVSS C:H/I:H/A:H confirma confidencialidad e impacto de datos.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
